Huawei shows off fast charging battery
 

Boffins in Huawei research and development subsidiary Watt Labs have developed a smartphone battery that can be recharged to half its capacity in just five minutes.

The company said that the battery uses the same lithium ion chemistry used in mobilephone batteries today but gets its advantage from atoms of graphite bonded to the anode.

This means faster charging but not at the expense of usage life or a sacrifice in the amount of energy that can be stored in each battery, it claimed.

One of the two batteries has a capacity of 3,000mAh (milliampere hours) and can be charged to 48 percent of capacity in five minutes. The second has a much smaller capacity of 600mAh but reaches 68 percent of capacity in just two minutes.
